Black Tufted Lichen Lichina pygmaea
Typically found on exposed sunny rock faces, the black tufted lichen looks rather like a seaweed, being fruticose (bushlike) in form with branching, brownish black, flattened lobes. Its fruiting bodies form in small swellings at its branch tips. The black tufted lichen is often seen growing in association with barnacles but does not tolerate algal (seaweed) growth. Its compact growth and rigid branches provide a refuge for several mollusks, particularly Lasaea rubra, a small, pink-shelled gastropod. All Lichina species are limited to coastal habitats.
